Description
Technical field
The present invention relates to settlement of foundation computing technique fields, more particularly to subsoil settlement prediction method, computer
Readable storage medium storing program for executing and terminal.
Background technique
Object can deform under the action of by ambient pressure, and similarly among architectural engineering, ground is by the external world
Certain deformation can also occur after the load of application, settlement of foundation is just called for the amount of this part deformation.In this deformation
During, effect of the soil by ambient pressure, there is a phenomenon where mutual extrusions, so that the gap between soil becomes smaller, it will
The discharge of moisture contained in soil.Such a process change structure of soil itself, changes water contained in soil
Point, for the process of this deformation, the deformation rule of external force according to suffered by it and soil, to the dependency number of settlement of foundation
According to being predicted, to guarantee the safety of Building Construction.Through that can send out the actual analysis of influence suffered by ground
Existing, the key for influencing settlement of foundation size is the spy that influence and the soil itself of ambient pressure suffered by soil have
Property two aspect.The case where ground is influenced by ambient pressure can be divided into again in terms of two: first, the shadow from fixation pressure
It rings.Structure trunk can form a pressure to ground, this pressure can be in fixed state after building completion,
Influence of such stress to ground is smaller in practice.Second, the influence of the active force from suddenly change.For example, underground water
Position changes so that active force suffered by ground changes；Can also ground be impacted by being vibrated.In practice,
The case where active force changes is the largest the influence of the ground of building.In addition, the characteristic that soil itself has is over the ground
Base settling amount also has an impact, and it is heavy all to influence ground for how many, soil structure of soil itself of the moisture as contained in soil etc.
The size of drop amount.
Due to the inhomogeneities of foundation soil, the difference of area of base safety stock, method for processing foundation be improper, building structure
The problem of designing improper and construction etc., any one problem therein are likely to lead to uneven settlement of foundation
Occur, building inclination will be caused, causes superstructure to generate additional stress or the increase of superstructure additional stress, when uneven
When sedimentation is more than the limit that building is born, that is, the accidents such as wall or flooring cracking are caused, or even make total knockdown,
It influences building to use, jeopardizes safety, therefore, when finding that ground has the sign of sedimentation, it is necessary to the sedimentation journey of composite foundation
Degree is predicted that the prediction technique of the settlement of foundation degree of the prior art is complex, and professional is needed just to be able to achieve.
Summary of the invention
Subsoil settlement prediction method, meter are provided it is an object of the invention to avoid shortcoming in the prior art
